Yes I currently am in a fallow period due to an ich/velvet outbreak. Will be out of it the beginning of March. Hence the restocking list. I currently have most of the fish in QT accept for a couple I’m questioning. But yes I am aware it’s a bit overstocked but I’ve maxed out my filtration so I believe it will Handel the extra bio load, I’ve got an Eshopps Adv 200 sump with a fuge and Eshopps x120 skimmer, I have to really try to keep nitrates and phosphates above 0 in this tank. (That’s before the fallow period) I had around the same number of fish before the outbreak all around the same size accept for the mandarins. As for the tang I did have a blue eyed kole tang however that was the tang that nuked my system with velvet. ( I have since learned the importance of proper QT…) the powder blue tank I got for a great deal and it’s been eating pellets and nori like crazy, super healthy fish.. but I am aware putting him in a 75G will soon become an issue but within a year I will be upgrading to a larger tank and in the meantime being in the 75 DT will be much better than the small QT he is currently in.
